Open LibraryClassic Algebra: Introduction to Linear Systems
Herb Gross introduces the topic of Systems of Equations in which there are two equations each of which has two variables. He shows how to solve such a system; i.e., find the value of each of the variables such that both equations are true simultaneously. Sometimes it is not possible to solve a system - either the equations are contradictory or do not admit a unique solution. Herb shows several examples of solutions techniques.
